(Added by the MultiSign amendment.)

A SignerList entry represents a list of parties that, as a group, are authorized to sign a transaction in place of an individual account. You can create, replace, or remove a signer list using a SignerListSet transaction.

SignerList Fields

In addition to the common fields, SignerList entries have the following fields:

Name JSON Type Internal Type Required? Description
LedgerEntryType String UInt16 Yes The value 0x0053, mapped to the string SignerList, indicates that this is a SignerList ledger entry.
OwnerNode String UInt64 Yes A hint indicating which page of the owner directory links to this object, in case the directory consists of multiple pages.
PreviousTxnID String Hash256 Yes The identifying hash of the transaction that most recently modified this object.
PreviousTxnLgrSeq Number UInt32 Yes The index of the ledger that contains the transaction that most recently modified this object.
SignerEntries Array Array Yes An array of Signer Entry objects representing the parties who are part of this signer list.
SignerListID Number UInt32 Yes An ID for this signer list. Currently always set to 0. If a future amendment allows multiple signer lists for an account, this may change.
SignerQuorum Number UInt32 Yes A target number for signer weights. To produce a valid signature for the owner of this SignerList, the signers must provide valid signatures whose weights sum to this value or more.

The SignerEntries may be any combination of funded and unfunded addresses that use either secp256k1 or ed25519 keys.

Signer Entry Object

Each member of the SignerEntries field is an object that describes that signer in the list. A Signer Entry has the following fields:

Name JSON Type Internal Type Description
Account String AccountID An XRP Ledger address whose signature contributes to the multi-signature. It does not need to be a funded address in the ledger.
SignerWeight Number UInt16 The weight of a signature from this signer. A multi-signature is only valid if the sum weight of the signatures provided meets or exceeds the signer list's SignerQuorum value.
WalletLocator String Hash256 (Optional) Arbitrary hexadecimal data. This can be used to identify the signer or for other, related purposes. (Added by the ExpandedSignerList amendment.)

When processing a multi-signed transaction, the server looks up the Account values with respect to the ledger at the time of transaction execution. If the address does not correspond to a funded AccountRoot ledger entry, then only the master private key associated with that address can be used to produce a valid signature. If the account does exist in the ledger, then it depends on the state of that account. If the account has a Regular Key configured, the Regular Key can be used. The account's master key can only be used if it is not disabled. A multi-signature cannot be used as part of another multi-signature.

SignerList Flags

(Added by the MultiSignReserve amendment.)

SignerList entries can have the following value in the Flags field:

Flag Name Hex Value Decimal Value Description
lsfOneOwnerCount 0x00010000 65536 If this flag is enabled, this SignerList counts as one item for purposes of the owner reserve. Otherwise, this list counts as N+2 items, where N is the number of signers it contains. This flag is automatically enabled if you add or update a signer list after the MultiSignReserve amendment is enabled.

Signer Lists and Reserves

A signer list contributes to its owner's reserve requirement. Removing the signer list frees up the reserve.

The MultiSignReserve amendment (enabled 2019-04-17) made it so each signer list counts as one item, regardless of how many members it has. As a result, the owner reserve for any signer list added or updated after this time is 2 XRP.

A signer list created before the MultiSignReserve amendment itself counts as two items towards the owner reserve, and each member of the list counts as one. As a result, the total owner reserve associated with an old signer list is anywhere from 3 times to 10 times as much as a new signer list. To update a signer list to use the new, reduced reserve, update the signer list by sending a SignerListSet transaction.

SignerList ID Format

The ID of a SignerList entry is the SHA-512Half of the following values, concatenated in order:

  • The RippleState space key (0x0053)
  • The AccountID of the owner of the signer list
  • The SignerListID (currently always 0)
